The inventipn relates to building construction, as described in the present specification and illustrated inthe accompanying drawings that form part of the same;

The invention consists essentially of the novel features of-construction pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to facilitate the construction'of walls, partitions and other parts of building requiring stanchions, beams or strips for supporting walls or wall surfacings; to maintain the wall or partition in good condition by the use of this support with modern building materials and methods of construction; to effect economy, in so far as labor and material are concerned,

2 and at the same time insure the stability of the structure to construct interiors withboth sound proof and fire proof properties and replace wood or other lnfiammable materigl wherever it is preferable to do so and espe ceilings and floors in which the stanchions and beams are concealed and dead air spacesdesirable; to adapt this metal studding to the modern form of wall board used in buildshowing the application of this invention in the construction of a partition. v

Figure 5 is a perspective strip.

Figure 6 is a sectional detail showing the assembly of a stud, the fastenings and the walls. s

Like numerals of reference indicate corresponding-parts in the various figures.

It will be seen that in every form of this invention the nail grips constitute the chief feature, the beams, stanchions, joists and rafters being formed to meet the different 7 applications, as for instance, the furring strip illustrated in Figures 5 and 6 is made of a detail of a furring long strip of sheet metal bent over itself transversely to meet in the centre and form the back plate 10 and the inturned flanges 11 and 12, these flanges being outwardly turned at 13 and 14 and curled at the ends into the gripping edges 15 and 16.

Thus the nail grip is between the offsets or spring grips 13 and 14,, while the gripping edges 15 and 16 on being spread by the nail dig into the ends of the wall boards.

In the application of this invention as a partition stud two sheets of metal are made in channel form, and these channels are applied to one another back to back and centrally secured.

v The beds of the channels are preferably offset inwardly at 17 to form shoulders, and

together the beds taper to the centre and the 'walls of the channels at the inner side form the aligning flanges 18 offset at their extremities 19.

The tapering beds mentioned aforesaid constitute the web of the stud in the secured position of the channels and it is between the web members that the desirable nail grips are formed from the one side or from the other of the stud.

The central fastening members 24 are here shown as tongues inserted in the slots 25, but

it is obvious that this is only one method of fastening the sheets together'for rivets will answer t e same purpose.

In this partition stud the metal is bent over itself inwardly towards the centre in a similar manner to the furring strip already described, and the outer walls of the channels form the aligning flanges 26 and 27, while the metal bent over forms the outer. flanges 28 and 29, which continue in the outward offsets and constitute spring grips or leaves 30 or 31 having the flaring curled ends 82 and 33 which dig into the ends of the boards.

In the application of a metal furring strip to modern construction the strip is fastened to the spacer 43 on the wall by the nails 44 through the double flanges 11 and 12 or by screws or rivets where the spacer is metal. The wall boards 45 and 46 of suitable material are brought into engagement with the gripping edges 15 and 16. The nails &7 are now driven between the spring grips or leaves into the spacer 43, and this spreads-the spring grips or leaves andsinks the gripping edges into the edge faces of the wall board, while the head of the nail enters the space between the wall boards which is filled in with cement 48 to insure a perfectly smooth surface throughout the whole wall. I

In the use of the partition stud, the wall boards 49 are shown on the one side and the wall boards 50 and 51 on the other side, with alternating joints respectively, and the aligning flanges 17 and 18 abut the wall boards 49 and maintain the aligned positions of said boards, and the nails 52 are driven in between the flanges 18 beyond the shoulders 17 and are securely gripped by the spring webs or leaves 21 and 22 within the said shoulders,-

so that they cannot come out.

At alternate sides of the partition the spring grips or leaves 30 and 31 engage the wall boards, and nails 53 are rigidly gripped by said leaves 30 and 31 and the webs or leaves 21 and 22, thus spreading the spring ceiling thereby maintaining the studding and consequently the walls in rigid positions.

The invention has been described herein as used in constructing walls and partitions in the most modern method, that is to say,

utilizing the wall boards so plentifully supplied in the building trade, and made up of many kinds of material, but the use of this stud is not by any means limited to wall boards, as the stanchion or beam described may be used generally, such as. for ceilings, floors or any other divisions or surfacings, the salient feature being the gripping and aligning of the parts as the nails or other fasteners are irremovably held to the stud, and

boards.

There are many Ways and places that this studding can be used, as it can be produced at an extremely low cost, thus taking the place of the more expensive wood studding, as well as furnishing all the advantages accruing to the metal construction.

livhat I claim is 1. In building construction, surfacing boards and frame members and a beam of sheet metal forming aligning flanges folded inwardly from either side and projecting outwardly in contiguous grips to flaring edges and nails inserted in said grips and spreading the; :1 to sink said flaring edges in the boards.

In building construction, a beam comprising a strip of spring sheet material formed with outturned longitudinal nail grips having flaring extremities adapted on the spreading 'of said ips to enter wall boards supported by sai beam,

3. In building construction, a stud formed of two strips of sheet metal/material centrally secured together and flanged at the sides having recesses on either side partially closed by gripping jaws and an elongated nail bushing of spear head shape in cross section and adapted to lock itself behind said jaws and grip the'nails. v Signed at Montreal, Canada, this ltlth da of October, 1928.
